Ramar, that's interesting about your 45 ACP cylinder, I'll have to try mine today & see how it does. If yours won't accept factory ammo I'd say it has to be short chambered unless there's some build up in the chambers from shooting.... You might try dropping some empty, sized cases in there to see how they fit if you haven't already, not sure what's going on. Our shooting range is owned by the city, it's an old gravel pit & they let us build the range on it if we would do the work. I was the first president & the first thing I did was take photo's & send them to the NRA & get our range insured. We have a wall about 25 feet tall at the end of our 300 yd targets that is a natural berm & beyond that is a Nature Conservatory for about 3 miles.....no houses! The city let us use their loader & one of the local mining plants furnished a bull dozer to level everything so we got it leveled & built lots of berms for the shooting bays. It's been about 15 years now but we have a very nice public shooting range, very little problems & we've never had a shooting accident. We're on our 4th president now & they just keep getting better.

Thanks for the suggestion, Dick. Tried empty brass and it fits fine. Chamber throats seem tight. Unless bullets taper immediately from the case mouth, they're tight. Oh well, the Colt cylinder works fine. Just fiddling...

Ramar, shot my 45 ACP cylinder for the first time today & was pleasantly surprised. I just took a few handloads for the 1911 & after shooting the steel clanger at 40 yds using the 45 Colt first I dropped the ACP cylinder in & gave it a test run. First up was some 230 gr tuncated cone bullets that shot just fine, the group wasn't all that great but a bad guy would have got shot 5 times. Next up was some 200 gr target loads like the old H&G 68 I believe. Anyway they not only shot great but shot to almost the same point of aim as my 45 Colt load. I liked it! I might be mistaken on the bullet weight, don't use this bullet much & it might weigh 185 grs, I'll pull one & see but either way it shot really good. No tight chambers, no problems at all, just a fine shooting ACP cylinder that I will use in the future. Here are the 2 targets, you can see they impacted almost exactly the same. Dick

Thanks for the report on your OM 45, Dick. I'm curious to know your experience if you get the ACP cylinder out. My OM 45's ACP cylinder seems to be too tight. I have to push bullets deep or the cartridge sticks out and the cylinder won't turn. Even with some factory cartridges. My OM 9mm cylinder is tight too. Your range is awesome! Simple fix is run a cylinder hone. Get one through Midwsy, attach to you hand drill with honing oil run it in and out each cylinder quickly, clean up and done.

Ruger 45 ACP cylinders are stepped inside, the case headspaces on the step and those cylinders are match grade tight. They also shoot match grade groups if you can see and hold them well enough. Don't alter the cylinder....load just for it. My first Ruger was a 45 convertible and both cylinders shot the same bullet to the same point of aim. If you've got one don't turn loose of it... try it out and shoot it.

Thanks for the report on your ACP cylinder, Dick. Your results and boolitdesigner’s comment give me hope my cylinder’s problem isn't insurmountable and it might provide excellent shooting with the right bullets. I have considered honing, jimtx. Done right (e.g., not by me ) it should at least enhance extraction. If I remember correctly, bullets in the factory loads that didn’t chamber were lead semi-wadcutters. Mine used these. Bullets have to be pushed deep, not leaving the shoulder exposed, or they wouldn’t chamber. ACP cylinder accepts 0.449 pin gauges in two chambers but only 0.448 in the other four. Lyman’s case gauge accepts my biggest pin gauge, 0.453, with room to spare. Guess they aren’t concerned with the bullet end of the cartridge? The 45 Colt cylinder only accepts 0.449 in all chambers but I haven't had issues with 0.452 bullets. Thanks again for your comments, guys. Apologies for hijacking your thread, Dick!
